I have been down this road. When we bought our Big Horn, it was our first fifth wheel... The truck we bought to pull it already had a B&W Turnover Ball Gooseneck hitch installed. After only a bit of research, we bought the Companion to go with it. I then proceeded to talk myself into the Bedsaver...after only a very short time. realized that the design of the Companion makes high hitching the fiver virtually impossible...if the jaws close and you can put the safety pin in the hitch, it is hitched...period...cutting to the chase, I would not buy a Bedsaver today to put on a Companion...
